Hi, I'm trying to setup a dual monitor configuration using xrandr 1.3 and catalyst 9.5 driver on a Mobility Radeon HD3470. Here's my xorg.conf:
Section "ServerLayout"
Identifier "X.org Configured"
Screen 0 "Screen0" 0 0
EndSection
Section "Device"
Identifier "HD3470"
Driver "fglrx"
BusID "PCI:1:0:0"
# Monitor options: radeon radeonhd catalyst
# laptop LVDS PANEL LCD
# external VGA-0 VGA_1 CRT1
Option "monitor-CRT1" "VGA"
Option "monitor-LCD" "LAPTOP"
EndSection
Section "Monitor"
Identifier "LAPTOP"
Option "PreferredMode" "1280x800"
#Option "DPMS" "true"
EndSection
Section "Monitor"
Identifier "VGA"
Option "PreferredMode" "1280x1024"
Option "RightOf" "LAPTOP"
EndSection
Section "Screen"
Identifier "Screen0"
Device "HD3470"
Monitor "LAPTOP"
DefaultDepth 24
SubSection "Display"
Modes "1280x800"
Depth 24
Virtual 2560 1024
EndSubSection
EndSection
The graphical environment starts, but the external monitor is black, even if I can move and see the mouse pointer on it. Here's the xrandr output:
$ xrandr
Screen 0: minimum 320 x 200, current 2560 x 1024, maximum 2560 x 1024

It seems a problem with xrandr, but turning off the external monitor with:
xrandr --output CRT1 --off
and then setting up by hand a dual screen with:
xrandr --output LCD --mode 1280x800 --output CRT1 --mode 1280x1024 --right-of LCD
everithing works fine. So I think it is a problem in my xorg.conf: I serched over the web but I found no useful information.
Can anyone please help me? Thanks

Did you report it or is it sb else?

just as a workaround, you can put the xrandr commands in your .xinitrc instead of your xorg.conf. This is how I've always done it and I've never had any problems.

Especially that you don't need xorg.conf anymore.

Really guys?? You are digging up a thread more than a year old and for what? Asking whether the OP reported a bug? Seriously?
